Simulation of microgrid system and low-cost wireless communication network
(2019-08-01)
The MATLAB/SIMULINK model of a microgrid system is presented in this thesis. The microgrid consists of a converter-fed distributed generator photovoltaic array with maximum power point tracking, a converter-fed battery ...
Optimal structure and efficient algorithm for max-min fair multi-group multicast beamforming
(2019-09-01)
In this thesis, we consider the max-min fair (MMF) multi-group multicast beamforming design to maximize the minimum signal-to-interference-plus-noise ratio (SINR) subject to transmit power limit. We obtain the optimal ...
Design and analysis of active aerodynamic control systems for increasing the safety of high-speed road vehicles
(2019-07-01)
The lateral stability and the safety of road vehicles is dependent on the vehicle design and operating conditions. Under operating conditions such as slippery roads, high lateral acceleration and tight cornering, the forces ...
Influence of sinusoidal motion on Stirling engines
(2018-12-01)
Stirling engines have a high potential to produce renewable energy due to their ability to use a wide range of sustainable heat sources and their high theoretical efficiencies. They have not yet achieved widespread use and ...
Analytical modelling of annular flow magnetorheological valves for advanced fluid control
(2019-08-01)
Magnetorheological valves have the potential to disrupt the fluid control industry with their numerous advantages over mechanical valves. The current design and development process of these valves largely leverages computer ...
Effect of diameter ratios on the flow-sound interaction of the straight circular finned cylinders
(2020-01-01)
Finned tubes that are widely used in heat exchangers could be susceptible to the flow-excited acoustic resonance that generates intense pressure fluctuations, which may lead to premature fatigue failure of the tubes. This ...
Thermal characterization and modeling of an energy storage system
(2020-09-01)
The thesis reports a virtual design tool that was developed to predict and analyze thermal loads in an electric vehicle charging system. The tool was designed using computational fluid dynamics techniques and validated ...
Probabilistic assessment of the impact of integrating large-scale high-power fast charging stations on the power quality in the electric power distribution systems
(2020-03-01)
The work presented in this thesis assesses the impacts of integrating large-scale high-power fast charging stations on the electric power quality by studying different power quality phenomena such as low-order and high-order ...
Development and validation of an Active Grille Shutter testing platform
(2020-09-01)
In this thesis, a testbench is developed for testing the functionality of Active Grille Shutters (AGS) and radiators in wind tunnels. Additionally, a generic pressure plate is designed to mimic commercial radiators, and a ...
Analysis and techniques of data compression in smart grids in the context of IEC 61850 communication protocol
(2020-02-01)
A smart grid is characterized by a two-way communication between the generation and the loads in addition to the distributed energy resources, which dictated the integration of smart monitoring devices to achieve full ...
